churn

Another word for turnover. For example, "It is said that about forty percent of U.S. job growth is in IT and that those in the industry change jobs on average every eighteen months, amounting to an increasingly high churn rate, compared with past decades." This term also means to produce something at a fast pace but with mediocre results, as in, "Some of those incubators thought that just by pooling office space and resources, they could churn out McStartups by the dozens. Boy, were they wrong."
